I am running CallManager 4.1(3)sr4b and am having an issue with certain phones updating with the DST. Mainly my 7940s. I have applied new firmware and reset the devices to no avail. Every other phone I have seems to have updated the time just fine (7960, 7961, 7970, etc...).
I will be upgrading to CUCM 7.3 in about 2 months, but that is too long to wait for the fix. Do I need to upgrade to CM 4.1(3)sr8a for the fix, or is the some type of workaround for the issue, hopefully without putting the affected phones ina seperate TZ or anything.
The DST note says you need to be past sr4d:
Cisco Phones - All Cisco Phones
For 7906, 7911, 7941, 7961, 7970, 7971, please note additional workaround
Cisco Unified CallManager - 3.3(x)
Includes SR's 3.3(5)SR2 and below
Cisco Unified CallManager - 4.0(X)
Cisco Unified CallManager - 4.1(x)
Includes SR's 4.1(3)SR4d and below
Cisco Unified CallManager - 4.2(x)
Includes SR's 4.2(3)SR1 and below
Cisco Unified Communications Manager - 4.3(x)
Cisco Unified Communications Manager - 5.0(4)
Cisco Unified Communications Manager - 5.1(x)
Cisco Unified Communications Manager - 6.0(x)
I also saw some old discussion of modifying the SQL table to adjust the dates, possibly workaround if you don't want to load the SR:
This problem for 7940's and 7960's was discovered yesterday AM. Here is a good description of the fix from [email protected] (I guess this was part of the OS Upgrade not mentioned in the Manual Workaround);
If the issue is only with 7940/60 phones, then we have seen a lot of similar cases today and are working to get a permanent fix to the issue. However as a workaround, you could resolve it by going into the Start >> Programs >> Microsoft SQL Server >> Enterprise Manager >> CCM database >> Table >> "TypeTimeZone" >> Right Click Open Table >> Return All Rows and manually set the "stddate" and "dstdate" to "0/11/0/1,2:0:0:0" and "0/3/0/2,2:0:0:0" respectively for each US timezone.
CM Service needs to be restarted.
From this long detailed thread;
Or, you could just wait a few weeks for them to catch up when they switch on the old schedule..
